(Phys.org) —An independent research team with members affiliated with several universities in the U.S. and Switzerland has concluded that the D-Wave Two computer shows no signs of quantum speedup. They've written a paper ...

(Phys.org) —Last week was a big one for space science, as it was announced that astronomers created the first realistic virtual universe—a computer simulation called "Illustris" that is able to recreate 13 billion years ...

With 2.5 million daily users, the Tor network is the world's most popular system for protecting Internet users' anonymity. For more than a decade, people living under repressive regimes have used Tor to conceal their Web-browsing ...

Random-access memory, or RAM, is where computers like to store the data they're working on. A processor can retrieve data from RAM tens of thousands of times more rapidly than it can from the computer's disk drive.

Comparing the genomes of different species—or different members of the same species—is the basis of a great deal of modern biology. DNA sequences that are conserved across species are likely to be functionally important, ...

It's hard to take a photo through a window without picking up reflections of the objects behind you. To solve that problem, professional photographers sometimes wrap their camera lenses in dark cloths affixed to windows by ...

Most recent advances in artificial intelligence—such as mobile apps that convert speech to text—are the result of machine learning, in which computers are turned loose on huge data sets to look for patterns.

A breakthrough by a team of researchers from UCLA, Columbia University and other institutions could lead to the more precise transfer of information in computer chips, as well as new types of optical materials for light emission ...

Physicists at the University of Sussex have tamed one of the most counterintuitive phenomena of modern science in their quest to develop a new generation of machines capable of revolutionizing the way we can solve many problems ...

For household robots ever to be practical, they'll need to be able to recognize the objects they're supposed to manipulate. But while object recognition is one of the most widely studied topics in artificial intelligence, ...
